Which of these do you prefer? I used fdroid but haven't installed a system ad blocker. I just use firefox focus which does a good job of preventing trackers and most ads but it's not perfect.
I have run AdAway for years. It works great and has great features such as auto-update of sites. It also lets you whitelist or blacklist additional domains locally.
Plus Samsung doesn't support is products. Last year I got a critical security update labeled july.. In December. And they have a bunch of garbage custom apps. Great hardware, poor service
